The patients were randomly divided into two groups: the ultrasonic bone scalpel group (\n                      <jats:italic>n<\/jats:italic>\n                      = 20) and the high-speed drill group (\n                      <jats:italic>n<\/jats:italic>\n                      = 20). Surgeons could not be blinded due to the nature of the intervention, but outcome assessors were blinded to group allocation where feasible. Surgical time, open-door time, intraoperative blood loss, postoperative drainage loss, post-operative complications, and functional outcomes were compared between the two groups.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      No statistically significant difference was observed between the two groups in terms of intraoperative blood loss, post-operative complications, screw migration, plate fracture, or spinal cord expansion. However, the ultrasonic bone scalpel group demonstrated significantly shorter surgical time, open-door time, and reduced postoperative drainage loss compared to the high-speed drill group (\n                      <jats:italic>p<\/jats:italic>\n                      &lt; .05). The reduced drainage volume may be attributed to thermal sealing of small vessels by the UBS rather than solely reduced tissue trauma. No significant differences were observed in the Visual Analog Scale (VAS) scores, bony union at the hinge, or Japanese Orthopedic Association (JOA) score improvement rates between the two groups at 1\u00a0week, 3\u00a0months, and 1\u00a0year postoperatively. While the UBS group showed numerical reductions in complication rates (e.g., dural tear: 0% vs 5%,\n                      <jats:italic>p<\/jats:italic>\n                      = .311), these differences did not reach statistical significance, likely due to the limited sample size.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The study concluded that USB significantly reduces operation time, open-door time, and postoperative drainage loss.
